• Visual Basic Region/Xml-comment Text Color Bug

  I found this weird bug the other day, which colors the text describing a #Region or an Xml-comment that is collapsed. The bug can be recreated like this: 1. Create a Project(e.g. VB Windows Application, the only one I tried) . 2. Create a #Region in the code and name it something, preferably a long string for more colors. 3. Collapse the region so that only the name of it is visible. 4. Place the input cursor above or in front of the region. 5. Press Ctrl+X until the line containing the collapsed region is cut to the clipboard. 6. Finally press Ctrl+Z to undo the deletion. -The description of the region should now be colored. Note: I have not found this bug to cause any damage to the project or source files. The coloring will disappe ...Show All

• Software Development for Windows Vista Custom composite activity

  I am trying to build an activity that contains some default business logic, but also includes the option for users to drop more activities into it. The problem is that I want to hide the default business logic activities, while still showing the user added activities. I have created this as a composite activity and have tried many designers. The closest solution so far has been a composite activity with a SequentialActivityDesigner. This allows activates to be added to it by users, but if I then add my business logic activities with my ActivityToolboxItem CreateComponentsCore, they will show on the activity. I have tried making my business logic activities hidden by overriding the isVisible property, but the still take up ...Show All

• Visual Studio 2008 (Pre-release) Input validation

  Hi, I would like to perform input validation before a service method is called. I have attributes on the MessageContract of the service that decides how validation should be performed, but would like to perform this before the actual method is called. I cannot do validation before the request values have been put inside an object of my MessageContract type. Is there an event that is suitable for this An interface I can implement Some samples on the net If you're using MessageContract's, you can define its members as properties instead of fields, and do the validation in its setters, like in the example below. Is it the case [ MessageContract ] public class MyMC { int age; [ MessageBodyMember ] public int ...Show All

• Visual C# Generating all possible character combinations

  Hi everyone, I just wanted to know if you have better ideas on generating all possible 4-character string combinations in C#. Something like: aaaa aaab aaac ... zzzz What i have in mind right now are nested for loops. I wonder if there is a .Net function for automatically incrementing characters/string. Thanks a lot. -Ver Thanks for the tip, anomolous. Yes, I did try that solution using Stringbuilder but somehow, I still would need to use nested for loops. Nothing wrong with that but I guess I couldn't generate a dynamic number of characters with the algorithm. Currently I have this block, where alphabet is a char[] and tester is a String. ...Show All

• SQL Server 2 sql server

  Hi In the company i work for we have 2 net and 2 server (server 2003) In the same net we have a net-harddisk where server 1 and server 2 can save data and so on we have a sql server on server1 and another sqlserver on server2 Now is the question: Can i have a database on the net-harddisk and then attach this dabase to sql1 and sql2 Regards Alvin Hi, one slight correction / addition, it is possible, but as H. already said not preferable to do this. You could enable la trace flag to make it working, but as network storages are in comparison to a local storage unreliable you should consider storing the data on a local hard disk driver or a certified SAN rather than a plain Shared folder on a network st ...Show All
